Part Number: TPS54A20 Tool/software: Dear TI experts,
I have several questions I would like to ask,
please see my below questions,
Does the capacitance value of the Series Capacitor in the TPS54A20 affect the circuit during load transients?…
Part Number: TPS54A20 Tool/software: We are considering using TI's TPS54A20 to implement a series capacitor buck converter and have a few questions for TI experts:
When selecting switches for a series capacitor buck converter, is SiC or GaN generally…
Part Number: TPS54A20 Hi TI Experts,
I have two questions about the resistance around the FB pin of the TPS54A20.
1. P32 of the TPS54A20 specification states "To reduce high-frequency noise, connect a resistor in series with the FB pin as shown…
Part Number: TPS54A20 Hi TI Experts,
I have 3 questions about the Efficiency around the VG pin of the TPS54A20.
1. It says that applying 5V to the VG+ pin turns off the internal LDO, which improves efficiency, but what is the loss of this LDO? …
Part Number: TPS54A20 Hello TI Expert,
I have a question about SCAP and AB phase drivers.
1. I would like to know how the SCAP charges 1/2 of Vin.
2. Do you agree that VGA and VG open the gate at 5V? Is it correct that VGA requires 5+VSCAP?
3…
Part Number: TPS54A20 Hi, TI expert
"8.2.2.10 Gate Drive Capacitor Selection" says to add a 1uF capacitor, but do I have to consider derating due to DC bias, etc.? Considering the DC bias, the EVM is 0.33uF. On the other hand, the capacitor I want…
Part Number: TPS54A20 Hi, TI expert.
The recommended output inductor is 220 to 350nH, but what happens if you use an inductor other than this recommended value? For example, what kind of behavior would you expect if you put in a 110nH inductor?
…
Part Number: TPS54A20
Hi,
I use a TPS54A20 on my design.
Here are the input parameters and the schematic:
Vin=12V
Vout=1.08V
Iout=3.4A (can be less or little more)
Fsw= 4MHz
This design has been simulated on Webench without I notice…
Part Number: TPS54A20 Hi, TI expert.
I would like to know how to connect AGND and PGND.
The GND is separate for analog and for high current, but in the end they are connected.
Therefore, I would like to ask you to tell me where it is recommended…
Part Number: TPS54A20 Hi, TI expert.
The rated power of all the resistors used in the evaluation board (TPS54A20-EVM770) is unified to 0.1W, but there is no point where the rated power is so necessary, right?
I don't think so, but please let me know…
